Application filed August 24, 1909. Serial No. 514,401.

To all whom it may concern:

Be it known that I, JosnPH GREGAN, of"

enable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in door checks and closers,theobject of the invention being to rovide sim le means which will enable aoor to be he (1 open to any desired extent and to so construct saidmeans that the same will operate automaticall to temporarily hold thedoor in open posltion but. which will yield upon the lapplication ofcomparatively moderate pres sure against the door to permit the closingof the latter.

A further object is to provide means on a door check for holding thedoor open and to so construct said means that the same can be readilyadjustedaccording to the extent it may be desired to temporarily holdthe door open.

. A further object is to rovide means on a door check for temporarilyholding a door open to any desired extent, said means being soconstructed and arranged that they can be thrown out of action and thedevice permitted to operate in the usual manner to close the door.

With these objects in view the invention consists in certain novel fatures of construction and combination's of parts as hereinafter setforth and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of a: door checkand closer showinthe aplplication of my improvements t ereto. ig. 2 is aplan view. Fig. 3 is a view partly in elevation and partly in section onthe line m-w of Fig. 2. B igs. 4, 5, 6, 7 and 8 are views illustratingmodifications.

1 represents the casing'of a door check and closer and 2 the spindle ofthe same, to which the lever arm 3 is secured,said lever arm beingadapted for cooperation with the mechanism of the device and forconnection with a door in the usual manner.

For the urpose of holding the lever arm 3 at any esired position andthus retainnow tobe described will be employed: The

cap or cover 5 of the casing 1 is provided with a lug. 6 which may besecured thereto or made inte a1 therewith and serve as a stop with. wich a spring-pressed dog 7 carried by the lever armcooperates. The dog 7in the form of the invention shown in Fig. 3, consists of a verticallymovable plunger mounted in a boss or enlargement 8 on the lever arm androvided at its lower end with two beveled aces 9, 9. A spring 10is-secured at one end to the lever arm by means of a screw 11 and at itsother end said spring is connected with the upper end of the dog orplunger 7 so as to normally press the latter downwardly so that itslower.

screw 12 passesfreely through a ho e in the lever arm and engages thesprin 10 intermediate the ends of the latter an the h of this screwserves as a stop to limit the upward movement of the spring.

From the construction and arrangement of parts above described, it willbe seen that when the door with which the lever arm is connected isopened, the lower end. of the dog or plunger 7 will engage one end ofthe lug or stop.6 and will be forced upwardly and then ride over the topface of said do or stop. When the lever arm has move suflieiently topermit the dog or plunger to pass the lug or stop, 'said dog or plungerwill be pressed downwardly. and become disposed behind the rear end ofthe lug or.

stop and thus the door will be held in open position. By applyingcomparatively moderate pressure to the door, the engagement of thebeveled face of the dog or plunger 7 with the lug or stop 6, the'saiddog or plunger will be caused to riseagainst the resistance of thespring 10'and to ride over the lug or stop. The device is now free tooperate to close the door in the usual manner.

In order that the door can be tem oraril y stopped at any desiredposition, it is necessary that provision shal be made to adjust the lugor stop 6. Such adjustment can be readily effected by turning the cap orcover of the casing and for the purpose of retainbig the cap or. cover1n any position to l which it may be adjusted, I provide av dog '13carried by one end of a spring 14 secured to the rim of the'cap orcover,said dog passing freely through a hole in the rim of 'the cap orcover and adapted to ent'er any one of a series of perforations 15around the upper end of the casing 1. I d

When it is desired that the door check and closer shall be operated inthe usual manner without being temporarily held open, the dog or plunger7 may be thrown out 0t action so as not to cooperate-with the lug orstop 6 on the cap, by loosening the.

screw 11 which connects the spring 10 with the lever arm.

Insteadof making the lockingdogin the form of a plunger as abovedescribed and locating the spring which operates the'dog, on top of thelever arm,'-said s ring may be secured to the under face 0 the leverarm, as shown at-16 Fig. 4 and the free end of this springprovided witha dog 17 to co- 0 eratewith the lug or stop on the cover of t e casing.V a Other means than those above described for efl'ecting adjustment ofthe stop or lug 6 may be employed. Thus in Fig. 5 the cap or ,cover isprovided in its flanged poror cast integral with tion with a series ofnotches 18vwith any one of which a locking dog 19 attached to the casing1 may be made to engage.

In Fig. 6 the lug or stop'is located on aplate 20 which is mounted uponthe cap or cover of the casing and adjustably secured thereto by meansof a pin 21.

In the form of the invention shown in" 7 the cap or cover of the casingis provi ed with a number of notches 22, into any one of which the dogor plunger carried by the lever arm may engage and thus hold the door atany desired open position, and in Fig. v8 I have reversed the--construction shown in the other figures, that is to say I have securedthe spring arm 10 to the underside of cap 5, with the spring pressed dog7 carried on the free end of the spring and projecting upwardly througha hole in the cap to engage a In or stop 6* fixed to ie underside of thelever arm.

It is evident thatchanges in the constructionjand relative arrangementof the several parts might be made without avoidingamy invention andhence I would have it understood that I do not restrict myself to theparticular construction and arrangement of parts shown and described,but,-

Having fully described my invention what -I claim as 'new and desire tosecure by Let- Y ters-Patent, is,

1'. In a door closer, the combination with a casing,'and alever arm, ofa yielding device including a dog carried by one of said parts andengaging a shoulder on the other part whereby the door may be yieldinglyheld in its open position, and means for adjusting the tension of saidyielding device hol .stop to temporarily lock the lever arm the wherebythe pressure required to close the door may be adjusted and regulated.

2. In a door closer the combination with a casing and a lever arm, of ayielding device including a dog carried by one of said parts andengaging a shoulder on the other part for yieldingly holding the dooropen, and means for changing or adjusting the position of the shoulderwith relation to the yielding: device, the construction of the shoulderand yielding device being such that a sufiicient pressure applied to thedoor will cause the yielding device to ride over the shoulder and thuspermit the door tobe closed. a

3. In a door closer, the combination with a casin having a stop, arotatable device and a ever arm connected with said rota table device,of a spring armsecured at one end to said lever arm, with itsfree endadjacent the casing, and a stop carried by the free end of said springarm and cooperating wit the stop on the casing for yieldingly the doorin open position.
